Q. I want to start selling items through eBay. I saw a program that develops PowerSellers. The company says I will have unlimited access to consultants. It also guarantees that I will double my investment in 90 days. The company has a great rating at the Better Business Bureau. But the program costs $1,400. I'm worried that it might be a scam. Should I take the plunge? Or should I avoid it?
